Ficinia nodosa

Ficinia nodosa, or Knobby Club-rush, is a hardy, clump-forming perennial sedge native to Australia, often found in coastal dunes, wetlands, and along waterways. Growing up to 1 meter tall, it features upright, dark green cylindrical stems and small, rounded brown flower clusters near the stem tips that bloom year-round, adding subtle structure to the landscape.

Knobby Club-rush thrives in well-drained to waterlogged soils and tolerates full sun to partial shade, as well as saline conditions, making it highly versatile. It is widely used in raingardens, where its dense root system aids in stormwater filtration, reduces runoff, and improves water quality. The plant also stabilizes soils, making it ideal for erosion control in riparian zones and coastal areas, while providing habitat for insects and small fauna.

With its resilience, ecological benefits, and ability to enhance water-sensitive urban designs, Ficinia nodosa is a valuable choice for sustainable landscaping, raingardens, and biodiversity-focused projects.
